@ -185,6 +185,8 @@ driver returns ENOIOCTLCMD. Some common examples:
hardware in the irq_set_freq function. If it isn't, return -EINVAL. If
you cannot actually change the frequency, do not define irq_set_freq.
* RTC_PIE_ON, RTC_PIE_OFF: the irq_set_state function will be called.
If all else fails, check out the rtc-test.c driver!
